And very similar to a device mentioned in linux-2.4.18/drivers/usb/storage/unusual_devs.h which is product id 3.
I've tried adding a section to unusual_devs.h as suggested by Alan Stern in the above message. That section is:
/* Same as above, for product id 5, seems to have similar problem.
* Needed for START_STOP flag */
UNUSUAL_DEV( 0x0c76, 0x0005, 0x0100, 0x0100,
"JMTek",
"USBDrive",
US_SC_SCSI, US_PR_BULK, NULL,
US_FL_START_STOP | US_FL_MODE_XLATE ),However, the usb-storage kernel thread still hangs in disk wait when the device is connected. Oddly, this happens only on some machines even though I've tried on several with the same architecture. The usb controller is:
Intel Corporation 82371AB PIIX4 USB
It seems that this usb-storage device has already caused some consternation, perhaps I've found another revision that needs special attention? See below for logs.
Thanks in advance for any tips, Alex Eagle
